IMPROVEMENT'IN APPARATUS FOR DRAINING SUGAR.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES B. HILL, of the city and county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Sugar-Mills; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon. v

The nature of my invention consists in the combination and arrangement of a hopper, conductors, valves, scraper, revolving screen, and cylinder, surrounded with a case; the whole being constructed, arranged, comf bined, and operating in the manner hereinafter described.

`To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation. In the accompanying drawings, which form part of my specification- Figure 1 represents a side elevation Of my improved sugar-mill. i

Figure 2 represents a transverse section ofthe same, cut through at line XX.

In the drawings, A represents the frame of the mill. B represents a case, which surrounds the screen R, which resembles a section of a drum. The sides of this screen re 'made of ne open work, and it is secured on the shaft 0. In the end of the screen are a number of Openings, marked Q, which are used for admitting air into the interior of the screen. On the shaft O, and inside of the screen R, is Vplaced a distributing-drum, above which is placed a conductor, f, provided with a valveor gauge, z'. The conductorf is supported on a pedestal, x, secured to frame A. The hopper, marked C, is provided'with a conducting-pipe, e, and a. regulating-valve or gauge, d. TO the lower part of the case B is attached a pipe, t, which is used for conducting o' the molasses. On the bar n of the frame A is pivoted a scraper, S, which extends into the interior of the screen, and set obliquely to the plane of the screen, so that it will, when held down on the screen, cause thesugar to run into i the chute li, and from it into a suitable collecting-vessel.

As the construction and arrangement of the several parts of my improved mill will be readilyunderstood by the skillful mechanic, I will therefore, without further description of its construction, proceed to describe its Operation.

Having all things constructed, arranged, and combined, as hereinbefore described, I put granulated molassses in the hopper C, and then, by means of suitable driving-gear, imparta rapid motion tothe shaft O, which will impart motion to the distributing-drum P and screen R. I then Open the valve or gauge d, which will allow the molasses tO iow through pipe or conductor into the eonduetorf. I then draw out the valve z', so as to allow the desired quantity of molasses to 'drop On the distributing-drum P, from which it is thrown off against the screen It, which will separate andy draw the molasses from the sugar; the sugar being collected on the inside of the'screen, and the molasses, dropping down in c'ase C, passes out through pipe tinto a suitable vessel provided i'or its reception. When any quantity of sugar is collected on the inside ofthe screen, I bring the scraper i S down, which will cause the sugar to pass Oft' through chute h into a suitable vessel provided for its reception.

In distributing the molasses on the drum P, the valve i should be moved in and out, so as to distribute the molasses along on the drum P, which cause an even distribution of the molasses against the screen.

Having thus described the nature, V'c Q'Iis'tructiOn, and operation of myV improvement, what I claim as of my invention, is

K The combination and arrangement of the hopper C, provided with valve d, case B, screen R, distributingdrum P, distributor f, provided with valve z', scraper S, chute 7i, and pipe t, the whole being constructed, i arranged, and operating substantially in the manner herein described, and for the purpose set forth.

' JAMES B. HILL.
